BENJAMIN WOLHAUfTER, OF NEW YORK, ,N. Y.

AN'JJLCREEIEING nnvrcn Fort RAILS.

To all whom itmay concern:

Be it known that I. Bnxmmx lVoLi-Lror- 'rrn, acitizen of the UnitedStates; residing at New York city, in the county of New York and Stateof Xew York, have invented certain new and useful Improvements inAnticreeping Devices for Rails, of which the following is aspecification.

The invention relates to means for obviating the tendency of railroadrails to creep l longitudinally, and it is one of the objects to providea simple device. that will otfectively hold a rail, is readilyapplicable to rails of the ordinary character now in general use,without changing or altering them, and when in position, willeffectively maintain such position.

The preferred form of construction is illustrated in the accompanyingdrawings, wherein Figure l is a side elevation of a portion of a rail,showing the device in operative position thereon. Fig. 2 is a crosssectional view of the rail illustrating the device partially in section.

' Similar reference numerals designate corresponding. parts in all thefigures of the portions 11.

d rawmgs.

The portion of the rail illustrated, is designated 3, and is providedwith the usual base flange mounted upon cross ties, a portion of oneofwhich is illustrated as at 5.

The device in the embodiment disclosed consists of a pair ofrail-embracing jaws or clips 6 which are provided with depending headsor nuts T that extend beneath the base flange of the rail, and havealined openings 8 therethrongh. These. heads also have opposite or rightand left internal threads 9, which as shown, are formed of spacedsections 10, leaving between them, open slotted A connecting device, inthe form of a rotary bolt 12, has its ends oppositely threaded tocorrespond to the threads of the jaws and said threads are also formedinto sections 13, which are spaced apart, forming slots or channels l-ftbetween them.

I The sections 13 are so arranged that they will slide longitudinally inthe slots between the sections 10 of theinternal threads of the jaws andin like manner, said sections 10 will be slidably receivedin the slotsor channels 14; formed between the sections 13 when the parts areproperly alined. Uponrot-ation, however, the sets of thread sectionswill move into interlocking or threaded engage- Specification of LettersPatent.

i ment, as will be obvious by reference to Fig.

thread sections 13 are provided with inclined rear faces and fiat innershoulders 15, while the jaws have cooperating opposite fiat videdbetween the threads. with an 0 set arm 17, and this arm carries at itsend, an I integral bearing foot- 18' that abuts against a cross tie, as5. j

In applying the device, the bolt is rotated until the sections of thethreads thereof are upon thebolts until theyare properly engaged withthe base'flange of the rail. The bolt is then rotated and the foot l8-is brought a ainst the side; of a cross tie, as shown. with this devicetherefore, a will be Obvious that if there is any tendency on the part17 will be turned, thereby partially rotating the bolt 12, and this willcause the jaws to be relatively moved toward each other so that theyWill effectively grip. the rail,and prevent its longitudinal movement.

The specific thread-formation described and suggested provides a.construction of suflicient, strength to resist the strainsincipermitting the screw action referred to.

construction, operation and many advantages of the herein describedinvention will. be apparent to those skilled in the art, without furtherdescription, and it will be understood that various changes in the size,shape, proportion and minor details of construction may beresorted-to'without departadvantages of the invention.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

1. An anti-creeping device for rails, comprising rail-engaging elements,and a rotatablemember connecting the elements and effecting theirgripping action upon the rail when said rail is moved longitudinally.

2. An anti-creeping device for rails, comprising rail-engaging elements,a rotatable member connecting the. elements and effecting their grippingaction upon the rail, and means for automatically rotating said memberupon the tendency of the rail to move longitudinally.

1. In the preferred form of constructionthe out of register with thethread sectionsof the j aws, whereupon said jaws can he slipped of therail to creep longitudinally, the arm'- dent to thisaction, while at thesame time,

ing from the spirit or sacrificing any of theshoulders 16. Theconnecting bolt 12 is )1'0- I From the foregoing, it is thought that thei iio u 7 a. An antl-creeping device tor ralls, comprising rail-embracng elements, and a rotatable member connecting the elements and threadedengagement with one of said ele-' ments, and a tie-engaging actuatingdevice connected to the rotary member.

v 5. An anti-creeping device for rails, comprising rail-embracing aws, arotary bolt threaded to both jaws, and an actuating arm carried by thebolt and having a tie engaging portion.

6. An anti-creeping device for rails, comprising a rail-clamping jawhaving an internal mutilated thread, and means for drawing the jaw intobinding engagement with the rail, including a. bolt having a mutilatedthread that is movable into and out of coaction with the threads of thejaw, and means for moving the bolt.

7. An anti-creeping device for rails, comprising a rail-clamping jawhaving a depending head that is provided with an opening an internalmutilated threads formed of spaced sections, a bolt that engages in theopening of the head and has mutilated threads composed of sections thatare slidprising rail-embraeing jaws having opposite internal threads, arotatable bolt connecting the jaws and having opposite threadsengagingthe threads of said jaws and an arm car-'- .ried by the bolt andhavlnga tie-engaging foot.

9. An anti-creeping devlce tor ralls, comprising rail-embracing jawshaving depending heads, said heads being provided with openings andinternal mutilated threads formed of spaced sections, the threads beingoppositely disposed, a bolt having oppositely disposed mutilated threadsupon its ends, said threads being formed of sections that are slidablebetween the sections of the internal threads and are rotatable into engagementwith the same, the threads having flat bearing shoulders, an armprojecting from the bolt between the jaws, and a curved t e-engagingfoot carried by the arm.

In testimony whereof I hereunto affix my signature in the presence oftwo witnesses. BENJAMIN \VOLHAUPTER.
